What do people do when they are 14, or 16?
Here, in Samut Prakan, at one of those dingy Eua Artorn flats for low-income earners, a 14-year-old girl convinced her 16-year-old boyfriend to kill her mother because she was "obstructing their love".
The girl's older 23-year-old brother was also stabbed several times as he tried to help his mother.
